Data Gaps

There were two data gaps this week. One a 20 minutes gap on 09/18/10 during a Wallops pass. The data appear to be lost.

A second data gap occurred on 09/20/10 between 12:50 and 15:15. This data is on the ground and will be reprocessed soon.


No HV commands this week. A spin-up of the spacecraft was performed on 09/22/10. We are still in normal/vigorous decimation and taking 4 minutes event data at the start and end of RHESSI night.
